Some foreign companies began to use the fragrance of the products to attract people's attention.
Unilever Germany uses the rub-and-sniff technology created by Scentisphere to add flavor to the packaging of certain products. Only when these areas are rubbed will the scent be released. The company hopes to add the taste of the product to the package as needed, thereby avoiding customers directly opening the package to smell it.
ScentSational, a packaging company in Pennsylvania, invented a method that can directly add FDA-verified flavours to food and beverage packaging, and can also add flavours to the packaging of consumer products. . The U.S. military hopes to use this technology to produce food packaging for the military, thus encouraging soldiers to eat more food on the battlefield.
NutriSystem is a catering company that hopes to use this technology to attract customers to drink the water they provide every day. The taste of fruit (lime, peach, or strawberry) is buried in the bottle cap. After 30 days, the thick fragrance will evaporate, but the water in the bottle will also bring fruit aroma.
